DRINKING-CUP.

Specification of Letters Patent.

Patented J an. 14, 1913.,

To all whom it may concern:

Be it known that I, CYRUS A. BRYANT, a citizen of the United States, and a resident of Passaic, in the county of Passaic-and State of New Jersey, have invented a new and Improved Drinking-Cup, of which the following is a full, clear, and exact description.

Theobject of the invention is to provide a new and improved drinking cup-preferably of paraflin paper or other similar waterproof material, and arranged to permit of nesting a large number of cups in a comparatively small space, the said method permitting of manufacturing the cup at a low expense.

The drinking cup is in the form of the frustum of a cone and formed from a single sheet of paper or similar material doubled up and having sides connected with each other, the bottom being fiat and onto which fold ears fastened in place by a separate disk, glued, pasted or otherwise fastened to the said flat bottom and the overlapping ears.

A practical embodiment of the invention is represented in the accompanying draw- 7 ings forming apart of thisspecification, in

which similar characters of reference indicate corresponding parts in all the views.

Figure l is a side elevation of a flat vessel made from a single sheet of paper or other material; Fig. 2 is an edge view of the same, partly opened up; Fig. 3 is a perspective view of the same after being fully opened; Fig. 4 is a like view of the same after the ears are pressed inward and down onto the closed fiat end of the vessel; Fig. 5 is a perspective view of the finished drinking cup upside down; Fig. 6 is a like view of the same right side up; and Fig. 7 is a plan view of the same.

The drinkin cup is formed from a single sheet of paragn paper or other material rendered waterproof, the sheet being doubled up, and one of the doubled-up members being provided at the sides with side flanges A folded onto the other member and fastened thereto to form a flat vessel, as shown in Fig. 1, the vessel having sides A a closed end A and an open end A*.

The closed end A is in the form of a sharp edge, and in order to form this flat vessel into a drinking cup of the shape of the frustum of a cone, I proceed as follows: The sides A of the flat vessel A are exteriorly engaged by suction devices B ad-- the middle portion of the closed end A by a suitable pressing device D so that the vessel is pressed down on the form C and the air confined in the closed end of the vessel is compressed to cause the vessel to open up fully at the closed end with a view to conform to the conical shape of the form C. By this downward pressure on the end A of the vessel A the closed end A is,

formed into a flat bottom A of approximately disk shape with the sides forming upwardly-extending cars A, owing to the fact that the said sides are not subjected to pressure by the pressing device D. Suitable fingers E now engage the ears A at the outer sides thereof to press the ears A inward and downward onto the flat bottomA of the vessel, as plainly indicated in Fig. 4.

It is understood that when the vessel is pressed down on the form C the air is compressed sutlicient-ly to open up the closed end of the vessel, at the same time allowing the air to escape between the inner surface of the sides A of the vessel and the outer surface of the form.

After the vessel has been given the shape of the frustum of a cone, as described, a fastening disk F, of paper or other similar material, is pasted, glued or otherwise attached to the bottom of the drinking cup so as to hold the ears A down upon the fiat bottom AF.

By constructing the drinking cup in the manner described, a large number of such cups can be readily nested to take up very little room, and by the method described the drinking cup can be cheaply manufac tured and sold at a low price.

It is understood that drinking cups of this kind are intended to be used but once and then thrown away, especially when a person makes use of public fountains or other similar water supplies,

Having thus described my invention,

claim as new and desire to secure by Letters Patent:

As an article of. manufacture, a drinking cup having a body in the form of a frustum of a cone and formed of a single sheet of paper doubled up, one of the doubled-up members having slde flanges folded onto and secured to the other doubled-up member, the

integral bottom of the cup being approximately in the shape of a disk formed of equal portionsof the said doubled-up members, and ears formed of portions ofthe j said flanges and portions of the said doubled-up members and fastened to the underside of the said bottom, the said ears being approximately triangular in shape and the apexes being spaced apart, and a bottom disk overlying the said ears and bottom and fastened thereto.

In testimony whereof have signed my name to this speeificationin the presence of two subscribing Witnesses.
